N.b., it's the stated policy of OpenStreetMap to not take information from Google... not primarily out of zealotry, but because Google's terms of service conflict with the ODBL license, and they don't want the organisation in legal trouble.

Normally this means no copying from Google Maps or Google's satellite or street-level imagery. (It also means no using Google's geocoding API if you have addresses that you want to add, but don't know where they should be added -- low-budget SEO companies tend to do this a lot.)

Using Google Translate -- and not even to translate, but just as a way to get copy-pastable handwriting recognition -- is a greyer area, but I probably would still recommend avoiding it. But nor do I know of any free alternatives offhand.
